Shattercane and grain sorghum [Sorghum bicolor (L.) Moench] seeds were buried at three depths for various times. Few grain sorghum seeds were viable 4 months after burial regardless of burial depth. None were viable 8 months after burial.

Only a few shattercane seeds from compact panicles were viable 4 months after burial, but some remained viable 3 years, mostly at the deeper burial depths (30.5 to 38.0 cm). Light was not a major requirement for germination after seeds were retrieved from burial regardless of time buried.

Some shattercane seeds from open panicles germinated after retrieval from all three burial depths even after 3 years. In general, number of viable seeds increased as depth of burial increased regardless of time buried. Germination, light-dependent in many wild cane seeds from open panicles, increased in light dependence with length of burial.
